Usability of Diabetes Dashboard Embedded Within a Patient Web Portal

Usability of Diabetes Dashboard Embedded Within a Patient Web Portal: A Prospective Longitudinal Study

The purpose of this study is to conduct a prospective, longitudinal study to evaluate the usability of a patient-facing diabetes dashboard delivered via an established patient web portal.

Up to 70 adult patients with type 2 diabetes mellitus will be enrolled and given access to a diabetes dashboard within an existing patient web portal. Patients will be invited by mail (or email) to be screened for enrollment in the study. Patients may also respond at a study flyer and contact the study team to be screened for enrollment. Eligible and interested patients will be emailed a link to a secure study website where they will complete a web consent form. After enrollment, participants will complete a baseline web-based questionnaire. After completing the enrollment questionnaire, they will be provided access to the diabetes dashboard within the patient web portal for one month. After one month, participants will receive an additional follow-up (final) questionnaire to assess outcomes.
